Pretty close to our design - just a bigger FPGA and a lot of other
nice
stuff on the DE1 which is one of my favorite platforms.

In fact the full Apple 2 implemented on DE1 is available for a long
time

All the sources are there. My quick VGA hack was actually a piece
of that project cut out and interfaced to the Apple bus instead of
generating its own clock.
It will be open source as soon as the new board is available and the
project is cleaned up a bit. So far it was just a proof of concept.
